I guess the blurred grid effect in TRON is due to MIP-Mapping
http://en.wikipedia.org/wiki/Mipmap
I remember to have seen blurred textures in the far in
some games. To reproduce this with just the SDL should be
some work, especially when trilinear filtering on the edges 
between different LOD images is desired.
